Always fascinating how they refer to themselves.
You have n-words.
Then potato n-words for the irish (and lithuatians)
Pasta n-words for italians
Bongs for the british
Leafs for canadians
Burgers and Amerimutts
Toothpaste for the netherlands
Gypsy for hungarians and romanians (who are at a perpetual shitposting war against each other)
Hohols for the ukranians
Finngolians
The usual suspects for anyone of any asian country, extra special hate towards the chinese and Xi's internet army.
and on and on
No matter what nation of the world you are from, they will find an insult for you. It's endearing in a way really.
Oh and also there's someone shitposting from a research facility in Antarctica.
